采用XPS、FTIR、H_2化学吸附和程序热还原等技术研究了以RuCl_3为前驱体制备的Ru/Al_2O_3催化剂浸渍后经不同处理后的催化性能。不同的钌物种（Ru-0，钌氧化物和氯氧化钌），金属分散和氯含量的催化剂，以及在它们的催化活性和选择性在苯选择加氢为环己烯，被发现根据所使用的制备程序。(C)2003 Elsevier Science B. V.保留所有权利。
The properties of Ru/Al2O3 catalysts prepared using RuCl3 as precursor and subjected to different treatments after impregnation, were studied using different techniques: XPS, FTIR, hydrogen chemisorption and thermal programmed reduction. Differences in the Ru species (Ru-0, ruthenium oxides and ruthenium oxychloride), metal dispersion and chlorine content in the catalysts as well as in their catalytic activity and selectivity during benzene selective hydrogenation to cyclohexene, were found according to the preparation procedure used.
